Yes, some manga is flipped, and some is printed Japanese-style. Kenshin is done Japanese style. It takes a little more work to follow, but not much. Though it did confuse me at first to figure out that if there are multiple dialog bubbles, they're all read right to left, too.

Do you get used to reading it backwards after a while? Incidentally, I used to read British versions of Marvel Comics and it was always funny seeing "pence" instead of "cents" on the cover. I've also seen some Spanish Marvels; I bet it'd be fun to read Japanese comics. I wonder if they have ads like American ones.
